About Us

Tether's software connects to parked Electric Vehicles -- coordinating the charging of thousands of vehicle batteries and turning them into flexible assets and the world's largest virtual power plant.
Our mission is simple:

We want to democratize the Energy Transition and empower individuals in the fight against Climate Change.

We are dreamers.

We believe in a more sustainable tomorrow - a tomorrow where everyone, no matter who or where you are, can contribute towards our goal of clean, resilient, and renewable power.

For too long, we have let special interests disrupt and dissuade real climate action and obfuscate the urgency of decarbonization;  and now, if we are to have any chance in solving the climate crisis, we need innovative and disruptive solutions to our big problems - and there is none bigger than the way we produce and consume energy. The old way of doing things can no longer be acceptable - and that's why we've built Tether.

At our company, we are committed to adopting the new, and we're not afraid to take risks - so we're opted to use the vast quantities of lithium batteries available in the growing numbers of Electric Vehicles to tackle this issue. This has never been done before, but by choosing to tap into this vast network of distributed consumers, we can decarbonize our grid without needing to rethink the whole system - and through directed, collective action.

We believe that climate leadership is not just about having an individual impact: it is about extending that reach and empowering millions of normal, like-minded individuals like us to come together and effect real, actionable change; that's what the democratization of the Energy Transition really means. So when we synchronize EVs to help stabilize the utility grid, reducing the need for compensating fossil fuels and allowing for the introduction of even more renewable power, that's not just a good business model - it's a statement to the core belief of this company:

By coming together, we can achieve great things.

Join us on this journey.
